In the vision app with Naza selected I check the IOC box but my S2 switch fails to activate the CL and HL modes. It was working earlier. No crashes or hard landings. I have a red/orange triangle flashing in the lower right corner of the app. I clicked on it but it doesn't do anything although it says click here for info. Compass still calibrates, and I connect to 9 satellites with the GPS, no camera issues. I really miss the course lock feature for video work.
